## Nitsche type mortaring for elliptic problems with corner singularities The paper deals with Nitsche type mortaring as a finite element method (FEM) for treating non-matching meshes of triangles at the interface of some domain decomposition. The approach is applied to the Poisson equation with D

We construct and analyse a mortar finite volume method for the discretization for selfadjoint elliptic boundary value problems in R 2 . This method is based on the mortar Crouzeix-Raviart non-conforming finite element spaces. We prove the optimal order H 1 -norm and L 2 -norm error estimates between
This paper is concerned with a specific finite element strategy for solving elliptic boundary value problems in domains with corners and edges. First, the anisotropic singular behaviour of the solution is described. Then the finite element method with anisotropic, graded meshes and piecewise linear
